Abstract[English]
The invention relates to a waste heat recovery arrangement (1) for an electric arc furnace (3). In order to increase the amount of waste heat that is recovered from exhaust gases from the electric arc furnace (3), the waste heat recovery arrangement (1) is provided with at least one forced circulation system (11) comprising at least one pump element (13) and at least one forced circulation duct (15) connected to the at least one pump element (13), wherein the forced circulation duct (15) is configured to absorb heat from exhaust gas of the electric arc furnace (3), and wherein the waste heat recovery arrangement (1) further comprises at least one waste heat recovery unit (25) downstream of the at least one forced circulation duct (15).[French]
